How do I procedural set y position.

<?xml version="1.0" encoding="UTF-8"?>
<Enemy>
	<monster>
	<name>bugaga</name>
	<hp>10</hp>
	<des>A vicious monster</des>
	</monster>

	<monster>
	<name>bugagi</name>
	<hp>25</hp>
	<des>a vicious and stronger monster></des> 
	</monster>
</Enemy>

Another problem
Id like to know how to set the instance variable based on the node without repeating the same value as the first node.

I know I can position it manualy but I have different set of monster xml so I need it the y position procedural every time I load different xml file. Thank you.
